# Industrial Specification: Vibration Exciter Unit

## 1. Technical Definition
A specialized component within a Quality Testing Station that generates controlled mechanical vibrations for product testing and validation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **5-2000 Hz frequency, 0.1-50 g acceleration, 0-100 N force**. Failure boundary: **Acceleration exceeding 60 g causes permanent magnet demagnetization, force exceeding 120 N causes armature coil insulation breakdown at 180°C**, Mechanism: **Lorentz force saturation in voice coil at 7.5 A current limit, eddy current heating in aluminum former exceeding 200°C Curie point for NdFeB magnets**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
